A 49-year-old woman was admitted for an electrophysiology study and ablation of recurrent episodes of symptomatic narrow complex tachycardia. Through a right inguinal vascular approach, a deflectable decapolar and a non-deflectable quadripolar electrophysiology catheter were placed into the cardiac chambers following the trajectory depicted in Fig. 1. In addition, using a right subclavian venous approach, a 4 mm non-irrigated tip ablation catheter (Celsius, Biosense Webster, USA) was used to map the triangle of Koch.

Typical atrioventricular nodal re-entrant tachycardia (AVNRT) was diagnosed at the electrophysiology study, and a slow pathway (SP) ablation was successfully performed at the right posteroseptal region in the usual fashion. There were no complications, and no recurrences of the tachycardia at follow-ups.
What is the vascular abnormality that accounts for the peculiar route through which the 2 electrophysiology catheters from the right inguinal region were placed in the heart?
